Indeed. Including, but perhaps not limited to, possibly offending your hosts/organizers when you don't drink the Pepsi they so carefully provided for you. In the Western world we might not care so much if he leaves a few sodas on the presenter's table. That may not fly so well in cultures that don't drink as much soda and abhor waste far more than we.
What did strike the most is how much this precise description of a conference organization is at odds with Asian culture. I guess rms would not be in his shoes in China for instance.
